One objectof this invention is ,to provide.

a brush adapted to be collapsed that it may enter the neck of a bottle and then expanded that the bristles of the brush may contact with the inner wall of the bottle to scrub the latter.

A further object of the invention is to com bine with the frame of the brush a pipe connection for the introduction of a cleansing fluid into the bottle while rotating the brush to scrub the latter.

A further object of the invention is to pr0- vide a plurality of radiating collapsible frames hinged to a slidable tube sleeved upon a pipe or nozzle through which water or other fluid is introduced into the bottle to be cleansed,-the construction being such that the several hinged radiating arms and bars of the folding brush may be simultaneously collapsed or opened by a longitudinal movement of said slidable tube upon the pipe or nozzle.

A further object of the invention is to provide a device adapted to be mechanically ro-' I tated and the folding frame of the brush automatically collapsed sufiiciently, to pass through the neck of a bottle and then automatically opened that the bristles of the brush may contact with the walls of the bottle,- the operation beingsuch that either the collapsible brush when opened may be shifted longitudinally within the bottle while rotating, or the bottle may be shifted longitudinally in relation tothe brush, the brush being then automatically collapsed for withdrawal from the bottle following a pre-determined period allowed for the scrubbing operation the mechanismv actuating the brush for performing these several operations being the subject matter of another application.

With the foregoing and other objects in view which will appear as the description proceeds, the invention further resides in the l combination'and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes may be made in the precise embodiment of the invention herein disclosed without departing from the spirit of the same.

, In the drawings accompanying this specification:

Figure 1 is a side elevation of the brush with parts broken away and in section, showing in full lines the brush in its 0 11 position so and in dotted lines,' its colla sib de portion closed for withdrawal from a ottle.

Figure 2 is a perspective view of a modification of the device, in which four radiating brush arms are emplo ed instead of two,-as I disclosed in the prece 'ng view.

Figure-3 is a diagrammatic view showing the brush expanded wit in a bottle,indicated in dotted lines,an also indicatin diagrammatically, means for mechanical y rotating the brush and for longitudinally shifting it that the device may be collapsed for removal or entry through the neck of a bottle. Figure 4 is a diagrammatic cross-sectional view taken on or about line 4-4 of Figure 3.

Figure 5 is an elevation of the cam,- shown partiall broken away in Figure 3, as viewed from a out line 55,for longitudinally shifting and collapsing the frame of the brush.

Figure 6 is a cross-sectional view taken on or about line 66 of Figure'3, showing dia-. grammatically, means forrotating the longitudinally slidable member sleeved on the pipe or nozzle. 8

Figure 7 is a fragmentary longitudinal sectional view taken on or about line 7-7 of Figure 1, indicating an abutment or stop provided on the nozzle to limit the movement of the slidable member controlling the opening and closing of the brush. At this point it may be stated that the several diagrammatic views-Figures 4 to v6-- are designed to make clear the respective corresponding elements indicated in Figure 3. Referring now to the letters of reference placed upon the drawings:

A denotes a pipe or nozzle of rectangular form in cross-section having at its forward endreduced apertures a through which water B is a sleeve member of similar form in cross-section having a limited slidable movement upon ,the pipe or nozzle. I

C, C are brush supporting arms-pivoted at C to the member Bhaving lugs C extending at right angles to the arms to limit the swinging movement of the latter upon the lugs contacting with the wall of the nozzle.

D, D are similar brusharms pivoted at D, D to the forward end of the nozzle.

E, E are connecting brush bars respectively pivoted to the arms 0, C and D, D at their outer ends.

F indicates bristles set in the arms C, D, and their connecting bars.

A is a raised abutment formed on the nozble A to limit the movement of the slidable member.

G denotes a circular disc carried by the member B which is adapted to rotate in a groove formed in a slidable element H supported in, suitable guideways I, I.

The slidable element H has a pin H projecting into a groove I formed in a cam I mounted on a shaft J, journalled in bearings J for supporting the shaft.

B denotes a relatively long circular sleeve on the end of the slidable member. B, driven by a frictional driving disc K on the shaft K j ournalled in bearings K for supporting the latter.

The sleeve B connected with the slidable member B maybe rotated by the frictional driving disc K while it is being shifted longitudinally upon the nozzle A to open and close the brush frame,it being noted that the rectangular shaped nozzle A has a circular formation at A adjacent its inner end fitted with a circular'collar A ,the circular end of the nozzle extending through the coug l pling nut L, which is in turn screwed to a supply pipe M,the nozzle being thus free to turn with the brush.

N indicates a washer "lodged within the coupling .nut to provide against leakage. P denotes a bottle indicated in dotted lines, with the brush expanded therein.

In the modification shown in Figure 2, instead of a single collapsible brush frame as indicated in Figure 1, a second frame of similar construction but projecting at right angles to the other frame is shown,otherwise the construction and operation ,ofthe device is identical with that shown in the preceding figure. I

In Figure 3 is graphically illustrated means for mechanically operating the brush whereby it may be collapsed to permit entry or withdrawal through the neck of a bottle,

also means for rotating the brush when inserted in the bottle.

Having indicated the several parts by ref- To insert the brush in the bottle,the slidable member B is shifted through the operation of the cam I to a position indicated by dotted lines in Figure 1, in which the several jointed brush bars lie adjacent to the wall of the nozzle. The brush may then be inserted in the neck of the bottle or the bottle pushed over the, brush as will be dependent upon the particular construction and operation of the machine in which the brush forms.

a part.

Upon the rotation of the cam the jointed frame carrying the brush bristles will be expanded within the bottle that it may con tact with and scrub the walls of the latter,

the water or other cleansing fluid entering the bottle simultaneously with the rotation of the brush. 1 j

Any suitable means may beprovided, if desired, for actuating the brush in the cleansing of a bottle or similar container.

It will be noted that the pipe or nozzle A and the sleeve B thereon are described as a more compact structure. Still further, this construction permits spaces to be provided on the elements against which other movable elements and their adjunctive parts may fit flatly and produce a most' compact device Y wh'en collapsed.
